Briefly describe the advantages of thermal spray technology

       Advantages of Thermal Spray Technology



1. The equipment is simple and can be constructed on site.



2. The process is flexible, the operation procedures are few, it can be repaired quickly, and the processing time is shortened.



3. Strong adaptability, generally not limited by the size and position of the workpiece.



4. Operational coating thickness.



5. In addition to spray welding, the heating temperature of the substrate is low, the deformation of the workpiece is small, and the metallographic structure and function change are small.



6. Various protective coatings and functional coatings can be prepared according to the appearance of various solid materials, which are suitable for various substrate materials.







Thermal spray technology features



From the principle and process analysis of thermal spraying technology, thermal spraying technology has the following characteristics.



1. Due to the wide temperature range of the heat source, the sprayable coating data contains almost all solid engineering data, such as metals, alloys, ceramics, cermets, plastics and composite materials composed of them. Therefore, various functions (such as wear resistance, corrosion resistance, high temperature resistance, oxidation resistance, insulation, heat insulation, biocompatibility, infrared absorption, etc.) can be imparted to the substrate.



2. (such as metal, ceramic, glass, cloth, paper, plastic, etc.) the appearance of the substrate is not too hot, it can be manipulated during the spraying process, so it can be used in various data (such as metal, ceramic, glass, cloth, paper, plastic, etc.) etc.), it has no effect on the arrangement and function of the substrate, and the deformation of the workpiece is also small.



3. The equipment is simple and the operation is flexible. It can not only spray large parts with large areas, but also spray on the designated parts. It can be sprayed indoors in the factory, or it can be applied on-site outdoors.



4. Fewer spraying processes, short construction time, high efficiency, economical and practical. With the improvement of thermal spraying requirements and the expansion of the scope, especially the continuous improvement of the spraying technology itself, such as the increasing spraying equipment, the gradual increase in the types of coating materials, and the gradual improvement of functions, thermal spraying technology has been improved in the past ten years. With the rapid development, not only the scope of use has been greatly expanded, but at the same time, these technologies have also been developed from the early preparation of general protective coatings to the preparation of various functional coatings. From single workpiece repair to mass production, from single coating preparation to spray system engineering, including product failure analysis, cosmetic pre-processing, coating data and equipment development, selection, coating system planning and post-coating processing , has become a very active topic in the field of data appearance science. In modern industry, independent data processing technologies such as casting, forging, welding, and heat treatment are gradually formed. It has become an important technical means for the industrial sector to save valuable data, save energy, improve product quality, extend product life, reduce costs and improve ergonomics. It has been more and more widely used in various fields of the national economy.
